Definitions

  • the invention relates to a method of manufacturing a part. hollow mechanics by diffusion welding and superplastic forming.
  • the present invention relates to the realization of a turbomachine hollow blade, in particular a rotor blade of blower, especially a wide-rope type dawn.
  • the welding-diffusion technique consists in put in contact at high temperature, under a certain pressure and for a while, two plates of a given material. Welding of the two plates then operates by diffusion of atoms, which presents the advantage of forming a binding structure equivalent to the structure of base of the material.
  • the anti-diffusion product forming a diffusion barrier and which is also called “stop-off”, is applied in areas predefined on at least one of the facing faces of the material plates superplastic so that, at the end of the diffusion-welding step, the plates are not welded in the areas covered with the anti-diffusion product which generally includes a charge of refractory material which inhibits the diffusion of atoms from the plates to be welded.
  • the assembly of selectively welded plates by diffusion welding is then usually subjected to superplastic forming by heating the assembly to a temperature compatible with a superplastic behavior of the plate material, in a mold generally closed.
  • An inert gas is then injected under pressure controlled in the non-welded areas of the assembly, thus allowing swelling of the plates according to the profile of the mold.
  • the quality of the weld from the of welding-diffusion depends on the operating parameters: temperature, pressure and time but also parameters related to the elements to assemble: metallurgical structure, surface condition (cleanliness, roughness). Consequently, it is essential to eliminate any source of contamination surfaces to be assembled before the temperature setting step diffusion welding.
  • an anti-diffusion product composed of a binder is used, generally organic, and a powder of an anti-diffusion material formed of a filler of refractory material such as a ceramic (for example of yttrium oxide, alumina or boron nitride or graphite).
  • a ceramic for example of yttrium oxide, alumina or boron nitride or graphite.
  • the binder After application of the anti-diffusion product according to a pattern predefined corresponding to the areas of the surfaces not to be linked by welding-diffusion, the binder is generally degraded so as not to retain as the powder of the anti-diffusion product, which has the properties anti-diffusion.
  • This application of the anti-diffusion product is carried out generally by the known screen printing technique which uses screen printing screens which include a frame surrounding a screen through which the fluid to be deposited passes in a predefined pattern.
  • the weft made by means of a canvas stretched in woven threads, presents clogged parts that block the passage of fluid in areas that do not must not be coated with anti-diffusion product.
  • This technique presents a resolution which depends in particular the mesh size of the weft and the diameter of the threads, the size of the mesh to be large enough to allow passage of fluid to deposit but small enough to reduce phenomena of "steps".
  • this screen printing technique requires a frame positioning system relative to the workpiece and multiple settings (canvas tension, distance between the canvas and the part ...), the canvas of screen printing undergoing wear over time which is manifested by a distortion which causes a shift of the deposited patterns.
  • step c) of peeling the non-welded zones causes small local tearing of the mask, which deteriorates the straightness of the deposit boundary.
  • step f) causes local collapses and / or uprooting of areas depot peripherals.
  • document EP0849029 proposes the application of the product anti-diffusion by a direct deposit produced by the process of fluid jets. This technique is close to the ink jet printing process since we use a movable print head above the plate, whose path is controlled by computer, the fluid being transferred by jets from a reservoir on the face of the plate in a pre-defined pattern.
  • this technique allows to deposit the product directly on the piece without the intermediary of a screen printing screen or a step prior to depositing a masking product, which simplifies the operation of filing and eliminating the manufacturing, maintenance and adjustment / control step of screen printing frames.
  • the present invention therefore aims to overcome the disadvantages of art anti-diffusion product deposition techniques previous, in particular without having to drastically control the viscosity of the anti-diffusion product.
  • the present invention relates to improving the conditions under which the welding-diffusion and in particular the present invention aims to contribute the elimination, before bringing the welding-diffusion temperature, of all source of contamination of the surfaces to be assembled, in particular residues from the degradation of the organic binder of the anti-diffusion product.
  • the present invention also aims to allow, so simple, reliable and with great precision, the deposit of the anti-diffusion product according to predefined patterns, especially with great clarity along the borders of these patterns.
  • such a method is easy to implement because that it simplifies the deposit step since it is possible to deposit the anti-diffusion product directly without the intermediary of a screen screen printing or a layer of masking product.
  • This solution therefore has the advantage, compared to the classic screen printing technique, to eliminate the manufacturing steps, maintenance and control and / or adjustment of screen printing frames.
  • the present invention does not present the risk of head plugging the print head.
  • sintering allows a good adhesion of the anti-diffusion product on the face (s) concerned (s) of the primary part (s), which eliminates completely the risks of migration of anti-diffusion particles in the areas that are to be welded by diffusion welding.
  • said anti-diffusion product comprises said powder and a binder and said powder is an anti-diffusion filler formed a refractory material comprising at least one of the materials belonging to the group composed of yttrium oxide, alumina, graphite and boron nitride, or any other powder in a material compatible with the substrate.
  • said anti-diffusion charge is a powder yttrium oxide whose particles have a medium size less than 50 ⁇ m.
  • said binder is not organic, it is aqueous-based and in particular said binder is water.
  • Such a binder indeed makes it possible to overcome the problems associated with elimination of degradation residues of organic binders. Indeed, when the binder is water, its elimination is carried out by evaporation during the passage of the laser beam.
  • step b1) application of a layer of the anti-diffusion product is carried out by a method known to those skilled in the art, for example by spraying, coating, screen printing etc ....
  • This arrangement can be implemented in a simple manner by means of spray nozzles which directly spray the product anti-diffusion over the entire surface of said at least one face of the parts primaries made of plates.
  • step b2) of sintering is carried out in air or, preferably, in an atmosphere neutral (of inert gas), in particular under an argon atmosphere.
  • step b3) of removing the unsintered product is performed by a non-abrasive operation, and this in order not to damage the surfaces to be welded by diffusion welding.
  • step b3) of removing the unsintered product is carried out by washing, which is a very simple.
  • This step b3) of removing the unsintered product can also be performed by any other action, in particular mechanical, not abrasive, such as brushing.
  • the laser is directed by a computer-controlled piloting system as it is already known in the field of laser marking.
  • said piloting system starts the course of the portion corresponding route within the said zone.
  • the present invention also relates to a method of manufacturing as defined above, characterized in that said part mechanical is a hollow turbomachine blade, in particular a blade fan rotor, and in step a) three parts are supplied primary (formed of plates) composed of a primary part upper surface, a central sheet and a primary lower surface.
  • Figures 1 and 2 relate to a hollow blade 10 of turbomachine, including a large-rope fan blade intended for example for a turbofan engine.
  • the blade 10 consists of a skin lower surface 12, upper surface skin 14 and central element 16 forming spacer.

  • the internal cavity 18 of dawn 10 has a radius 24 on the side of the leading edge 20 and a radius 26 of the trailing edge side 22.
  • the central element 16 forming a spacer comprises surfaces welded to the lower surface skin 12 and welded surfaces on the upper surface skin 14, which makes connections between portions of the central element 16, which form stiffeners, and the skins 12 and 14, with spokes 28 or 29.
  • the blade 10 visible in FIGS. 1 and 2 is produced from three primary parts (a primary upper part, the central plate 16 'and a primary lower face part) which are obtained by forging, stamping on press followed by machining for finishing.
  • a deposit of diffusion barriers is performed according to a predefined pattern corresponding to the regions of the faces primary upper and lower parts located opposite the cavity 18 and which will not be connected to the spacer element 16.
  • the step of depositing the anti-diffusion product as it has just been described in relation to FIGS. 4 to 6 and according to the sequence of operations b1) to b3) is carried out, in the case of the method of manufacturing a blade 10 such as illustrated in Figures 1 to 3, at least on two sides of the parts primary.
